Shade Gray Polarized Merritt Sunglasses – Black
A dark, neutral gray polarized lens in our black Merritt frame, for light-sensitive eyes that struggle with harsh sun and glare off roads, water and snow.
Shade Gray is a true sun lens that also blocks 99% of blue light across 400–500nm. Independently tested by Micro-Light Optics against ISO 12312-1, ANSI Z80.3 and AS/NZS 1067, it lets through 13% of visible light, a Category 3 lens built for bright days outdoors. It is not for driving at night or in low light.
The flexible TR90 frame weighs just 24g, light enough to wear for hours without pinching your nose or temples. A unisex square shape that suits most faces.

What to Expect
The dark gray tint takes a little getting used to. Light sensitivity is personal, so we recommend a 2–3 week trial. Each pair comes with one lens; the Sleep ZM range offers 14 lenses for different lighting, sold separately.
In the Box
Protective case, anti-fog cloth, and a blue light test card with mini flashlight so you can see the lens block blue light for yourself. Backed by Sleep ZM's 1-year manufacturer warranty.
A fraction of the price.
Light sensitivity buyers shopping the premium brands rarely realize there's an affordable, lab-certified alternative. Here's the math.
Sleep ZM is not affiliated with TheraSpecs or Axon Optics. Pricing reflects publicly listed entry-level non-prescription options at time of writing.
